SLLS686D October 2005 – July 2024 MAX3221E
PRODUCTION DATA
The MAX3221E is a single driver, single receiver RS-232 solution operating from a single VCC supply. The RS-232 pins provide IEC 61000-4-2 ESD protection. The device meets the requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial-port connector. The charge pump and four small external capacitors allow operation from a single 3V to 5.5V supply. These devices operate at data signaling rates up to 250kbit/s and a maximum of 30V/µs driver output slew rate.
Flexible control options for power management are available. Auto-power down disables driver and charge pump when the receiver is disconnected or the remote driver is power down. The drivers can be manually enabled or disabled. INVALID output goes low when receiver input is unconnected or power off.
